我创建了一个新的Android项目，一个空的活动项目并使用了StrictMode，但由于strictmode，应用程序每次都会崩溃。磁盘读取违规
我在空活动的setContentView上提出的类似问题的答案是严格模式磁盘读取冲突，其中解决方案是即时运行，但我使用的是Android studio 3.5.1和即时运行，替换为"应用更改"。
import androidx.appcompat.app.AppCompatActivity;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
if (BuildConfig.DEBUG) {
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
.detectDiskReads()
.detectDiskWrites()
.detectNetwork()
.penaltyLog()
.penaltyDeath()
.build());
StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
.detectLeakedSqlLiteObjects()
.detectLeakedClosableObjects()
.penaltyLog()
.penaltyDeath()
.build());
}
super.onCreate(savedInstanceState);
// setContentView(R.layout.activity_main);
}
}
这是我的日志猫，由以下原因引起：android.os.strictmode.DiskReadViolation

崩溃是由于 .penaltyDeath((。
如果您不打算在违反严格模式时使应用程序崩溃，请将其删除。
